PATENT SURN JACKSON, OF S'IOOKTON, CALIFORNIA.

PUMP.

SPECIFICATION forming part of Letters Patent No. 270,900dated January23,1883.

Application iled August 12, 1882. (No model.)

appertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specifica- My inventionrelates particularlyr to that class of pumps known to the trade assuction andlift(combination) pumps,in which water is raised from wellsof various depths by plungers and valves.

rlhe object of my invention is to simplify and cheapen and at the sametime to render more ei'ective the operation of such pumps.

My invention consists ot' a novel apparatus' for raising the water,which is accomplished by the use of particularly-constructed valves andplungers, in combination with certain other devices, such as will behereinafter described.

Referring to accompanyingdrawings, Figure l is a vertical sectional Viewof myentire ap paratus. Figs. 2, 3, 4, 'and 5 are detached views ofparts ot' Alower `valve, l\"ig. 2 being the top flange, Fig. 3 theclapper, Fig. 4 the bridge having guide for upper end of clapperstem,and Fig. 5 the bottom iiange with lugs and slots, and having` g'uide forlowerend of clapper-stem. Figs. 6, 7, S, and 9 are detached views of myAimproved plunger, Fig. 6 being section ot' plunger proper, showing thebolt that secures the bridge'to it, Fig. 7 being said bridge; Fig. 8 isclapper, and Fig. 9 is a vertical elevation ofthe plunger proper. l Fig.10 is a view of an improved clapper which may be used in the place ofthe one illustrated by Fig. 3, iF preferred. Fig. ll is a side elevation of one of the plungers.

My improved ,plunger consists of F, the plunger proper, and having f,the guide for lower end of clapper-stem, at its foot; G, the

clapper, consisting of a, the stem, and b and b, respectively, the upperand lower ianges, having theleather packing c between; H, the

bridge, having e, the guideof the upper end of steine ofclapper G; I,the bolt securing the bridge H toits position in plungerproper, F,thehead resting in aslot at the top ofthe forked portion ot' said plungerproper, F, and the nut upon the head of bridge H, the point of the boltfitting into a circular opening therea't, so as to admit of the freeplay of the nut upon the thread of the bolt I. g is leather packingsecured Ato its position over circular .foot ot' plunger F by 111e endsot` the forks of bridge H pressing thereon, and kept tightly to theirplace by screwing down the nut upon bolt I. The circular foot ot'plunger F contains the guidej' of lowerend ot' stem, a, of clapper (if.My improved lower valve consists of body A, the lower flange, A', havingthe four lugs carrying bolts securing it to E. B is the valve-seat,which rises to a suitable height above the body A, which has the slotsxmade through its flange y for the bolts z to catch in; B, the upperflange; '0, the clapper, consisting of flanges b and b, bolted together,with the leather c between, and stem a, the leather c `resting upon seatB; D,-the bridge, the roofof which has a round hole as guide for upperend of stem a of clapper O, the body A having the guide l forthe lowerend of said stem a.

Having described the various parts, I will now set forth the manner ofuse, together with my method ot' producing a continuous stream of water.i Any suitable style and size of piping is inserted in the well andsecured to the coupling ot' body A, which is secured to platform E (thecoupling` otl ange Aresting in an opening of platform E) by the boltsot' the lugs 'A'. By this method of fastening the body A to the frame Ethe lower valve and apparatus above mentioned may be removed by removingthe bolts e, and thus taking oft' the body A without disturbing the pipein the well. 'Ihecomplete clapper G is then placed in position byinserting the lowerend of itsstem a into guide d of body A. Bridge 1) isthen placed in position, the circular hole inits summit taking the upperend ot' stem a of clapper C and acting as its guide. B, the upper flangeattached t0 thelowerend ofapumpcylinder,is then placed in position, andsecured there by bolts passing down through slots of flangeA.' Myimproved plunger as first above described is then iii- TOC serted in thecylinder, and being properly connected with the usual plunger-rod thepump -is then ready for operation by the usualmethod as afsingle-actionpump; but should it be desired to use that portion of my invention asabove suggested,by which a continuous stream of water may be raised,another section of cylinder connected to upper end ofthe rst-men tionedcylinder by iianges J (having a bridge,) and J must 'be employed andanother of my im proved plun gers placed therein, and the two plungersconnected and operated by the following device: The upper plunger hasthe rod N connected toit, and is operated'in'the usual manner; butthelower piston iscaused to move downward by the combined help oftheweight of the water above it and the springsO while the upper piston isbeing raised upward, and

the lower piston is drawn upward as the up! per piston descends throughthe force that is exerted upon it by the pressure of the upper piston onthe rod M. This rod M has its upper end forked, so that the upper pistonwill 'press squarely upon it, and is guided in its vertical movements bythe guide I), which forms a part ot' or is secured to the flange J.

To thelower end ot the rod M is secured thecord, wire, or chain L, whichpasses .up over the pulley K, and then has its other end fastened to theupper end of the lower piston. Vhen the upper piston is forced downward,it strikes upon and forces the rod M downward, thereby drawing the lowerpiston upward through the cord, wire, or chain L. When the upper pistonis raised upward, the combined weight of water upon the lower piston andthe pull of the coiled springs C) draw and force the lower pistondownward, thereby forcing the rod M through the cord, wire, or chain Lupward.

By this above device and method a continuous stream of water is keptflowing from the nozzle ot' the upper section of the cylinderwhenevcrthepumpingapparatus,as described, is set in operation.

My devices may be applied to an ordinary forcepump by adding thenecessary packing vand piston at the head of the upper section ofcylinder.

In place ot' the clapper (l of the lower valve may be used,if preferred,a clapper, C', as shown iu Fig. 1.0, which consists of a clapper-stem,a',

with top flange, having secured to it by bolts a forked guide, b2', withleather c between it and the ange. This device fora clapperIconsidermore certain in its operation, being less liable to wear and lose itsposition.

WVhen it is desired to remove the clapper G from its position in theplunger, the nut of boltI is loosened on its thread, and thus permitsthe easy removal of clapper G. When it is desired to change from thedouble action to the single action, the driving-rod ot' the upperplunger may be sufficiently shortened, and thus prevent the plunger uponits downward stroke from reaehin g the head ofthe propeller M, whichwill cause lower plunger to lie dormant at the bottom of the lowersection ot' cylinder.

Having thus described myinvention, I claim and desire to secure byLetters Patentl. IThe combination of the body A, having the ange Af,valve-seat B', and ange y, having the slots w, with the platform E,flange B, bridge D, and valve, the parts being secured togethersubstantially as shown. l

2.y The combination ot' plunger F, provided with the guide j', andhaving a recess iu its side to receive the packing g, the bridge H, andbolt I with the valve or clapper, substantially as described.

3. rIhe combination of the upper plunger, a vertically-moving rod, l\[,alower piston,and a cord, wire, or chain, which connects the rod andlower piston together, and a guidefor the cord, the rod being entirelydisconnected from the upper piston, substantially as set forth.

4. The combination of the upper plunger, a vertically-movingrod,aconnecting cord, wire, or chain, and a guiding-pulley, the lower pistonor plunger, and the springs O, substantially as specified.

5. rThe combination ot' the upper plunger, a vertically moving rod, aconnecting cord, wire, or chain, a guiding-pulley and a suitable guidetherefor, and the lower plunger, substantially as shown.

In testimony whereof I affix my signaturein presence of two witnesses.
